Stalled/wants to stall at stop.

[thomas7.3psd]

The other day while coming to a stop my truck lost throttle response, It was still idling but it would not respond when i hit the throttle. I shifted it to nuetral and back to drive and it worked. The next day came to a stop sign and it stalled out. restarted right away. now when i come to stop its acting like the engine is coming under load and the rpms drop abit(maybe 100rpm) and the idle kinda bounces up and down. I have checked my connections to the chip, pedal,ipr,and transmission..ive driven it without the chip and though i could not get it to stall today its acting like it coming under load when coming to a stop....any help would be appriciated. thx


truck is a 02 7.3 4x4 with a BTS.

Any code kinda sounds like Gps

Throttle position sensor

Sounds like a CPS sensor to me.

changed the Cps same old thang..its dropping throttle response to idle under acceleration now..gonna pick up a pedal assembly tomorrow and see if that fixes it.

No don't fall into buying the assembly bondo grave yard sells the sensor cheap you done need the whole pedal

Lucky for me the pedal didnt match up..TSD and a few guys suggested to clean the IPR...been a few days without any problems..keeping my fingers crossed. thx for the input.
